17826 Normanwisdom           Discovered 1998 Apr. 3 by J. Broughton at Reedy Creek Observatory.
British comedy great Norman Wisdom (b. 1915) is best known for his smash hit films of the 1950s as the downtrodden, accident-prone little man in the shrunken suit and skewhiff cap. A physical comedian, Wisdom did his trademark trip-up on the red carpet after being knighted by the Queen.
